International ClassA61M 037/00AbstractAn elongate steerable implement is disclosed, which may be either a steerable guidewire or catheter for coronary angioplasty applications. A floppy steerable tip on a steering region at the distal end of the implement and a control device at the proximal end are connected by means of a plurality of axially movable deflection wires extending throughout the implement. Manipulation of the control permits deflection of the steering region throughout a full 360° range of motion about the axis of the implement, without axial rotation or "torquing" thereof. | |
